Create Interactive Web Maps with the JavaScript 'Leaflet' Library

Create and customize interactive maps using the 'Leaflet' JavaScript library and the 'htmlwidgets' package. These maps can be used directly from the R console, from 'RStudio', in Shiny applications and R Markdown documents.


An R Interface to Leaflet Maps

Build Status

Leaflet is an open-source JavaScript library for interactive maps. This R package makes it easy to create Leaflet maps from R.

m = leaflet() %>% addTiles()
m  # a map with the default OSM tile layer

m = m %>% setView(-93.65, 42.0285, zoom = 17)

m %>% addPopups(-93.65, 42.0285, 'Here is the <b>Department of Statistics</b>, ISU')


You can install this package from CRAN, or the development version from Github:

# CRAN version

# Or Github version
if (!require('devtools')) install.packages('devtools')


In addition to the usual R package documentation, we also have extensive docs and examples at: http://rstudio.github.io/leaflet You may use Github issues to file bug reports or feature requests, and ask questions on StackOverflow or in the Shiny mailing list.


To make additions or modifications to the JavaScript htmlwidgets binding layer, you must use Grunt to build and test. Please make sure Node.js is installed on your system, then run:

npm install -g grunt-cli
npm install

Now you can build/minify/lint/test using grunt build, or run in "watch" mode by just running grunt. JS sources go into javascript/src and tests go into javascript/tests.
